提出了机械进丸抛丸器堵丸现象和抛丸量、抛丸率低的主要原因是其固有的喂丸方式即分丸轮的结构造成的。设计出一种螺旋进丸抛丸器，对螺旋分丸轮的部分参数作了探索性试验。试验结果表明，螺旋进丸抛丸器改机械分丸轮的切向喂丸方式为轴向喂丸方式，提高弹丸的输送能力，减小了分丸轮对弹丸的挤压摩擦，从而较大幅度地提高了抛丸量和抛丸率，消除了堵丸现象。 The main reason that the mechanical shot pill shot blasting device blocks the shot phenomenon and the amount of shot blasting is low is the inherent feeding mode of shot pill. Designed a spiral shot pill shot blasting device, made some exploratory experiments on some parameters of spiral shot pill wheel. The test results show that the spiral shot pill shot blasting machine changes the mechanical shot pill wheel tangential feeding method for the axial feeding method to improve the projectile transport capacity and reduce the sub-shot wheel on the projectile extrusion friction and thus larger Magnitude increased the amount of shot blasting and shot blasting, eliminating the plug pill phenomenon.
